With Rocky Mountain National Park’s largest campground shutting down this summer for a modernization project, reducing available campsites on the eastern side of the park by more than half, ripple effects are apt to be felt at campgrounds across the Front Range. The closure of the Moraine Park Campground means 244 fewer sites for 2023, and it figures to put more pressure on nearby campgrounds in the adjacent Arapaho & Roosevelt National Forests, which spreads out along the Continental Divide from Clear Creek County to the Wyoming border, and it ranks as the third-busiest in the U.S. “Our reservable campgrounds are in high demand,” said Reid Armstrong, Arapaho & Roosevelt spokesperson.
